Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as it heats, giving it body.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
- Oyster juice
- Provides the main liquid and the briny oyster flavour of the sauce.
The step that matters
Heat gently until the mixture thickens. Flour thickens liquid by swelling its starch granules as they heat. Too much heat or too fast can scorch the butter and flour or leave lumps, so heat slowly and stir to keep the sauce smooth.
Swap the mace
How well each one fits the dish's main ingredients (oyster, flour, butter, pepper):
- Parsleyfits better
- Capersfits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against oyster, flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
